How long should a dyno tune take?
For a camshaft, I'd say a bare min of an hour street driving. It takes about 60-90 minutes to dial in MAF/VE tables, then blend them back together and do WOT.
BTW, if your tuner doesn't street tune first, go to somebody else.
WOT tuning is simple - timing and A/F. Tuning is for idle,drivability ect. Almost anybody can make dyno #'s.
